Arrowverse comes full circle with its first comic book crossover event, Earth-Prime

gamesradar.com:

The CW's DC television shows are coming full circle to a comic book event set in the canon of the Arrowverse universe. 

Launching April 5, Earth-Prime is a three-month, six-issue event with the first five issues spotlighting a current individual CW/DC series, with the final issue (Earth-Prime #6) being a full-on Arrowverse crossover.

Actors, writers, and even showrunners from the shows will be involved in the creation of each double-sized issue approved by the show's producers. 

With the unlimited possibilities of comic books, the event could potentially feature characters, settings, and action sequences not possible on the budgets of weekly TV series and could also include the possible returns of characters from Arrow, Supergirl, and Black Lightning, all series no longer in production. 

DC has released information about the first two issues both on sale in April. Here's a rundown:

The event kicks off April 5 with Earth-Prime #1, featuring characters from the Batwoman TV series. The story stars the titular new Batwoman (Ryan Wilder) dealing with classic Batman villain Clayface (making his Arrowverse in-continuity debut) who binds himself to a local high school student along with Luke Fox who deals with being both a new superhero and a boyfriend. 

Earth-Prime #1 will be written by show writers Natalie Abrams and Kelly Larson, along with the Luke Fox/Batwing actor Camrus Johnson. Comic book veteran Clayton Henry draws the issue.

In this episo– err, issue - of Earth-Prime, Clark Kent and Lois Lane celebrate their first wedding anniversary but are pulled off track by their respective careers as superhero and reporter. Plus the origins of the evil Superman variant from Earth-TUD22 that's been teased in the first two seasons
